Virial coefficients of Lennard-Jones mixtures

摘要: We report results of calculations the second through sixth virial coefficients for four prototype Lennard-Jones (LJ) mixtures that have been subject previous studies in literature. Values are reported temperatures ranging from T=0.6 to T=10.0, where here temperature is given units LJ energy parameter one components. Thermodynamic stability studied using equation state (VEOS) with calculated coefficients, particular focus on characterizing vapor-liquid critical behavior mixtures. For three mixtures, coexistence and data available comparison at only temperature, while fourth we can compare a line. find VEOS provides useful indication presence location behavior, although some situations need consider “near-miss” classical conditions criticality nearly but not exactly satis...
